Question 2

A square shaped park ABCD of side 100 m has two equal rectangular flower beds each of size 10 m $\times$5 m (see the figure). Length of the boundary of the remaining park is

(a) 360 m

(b) 400 m

(c) 340 m

(d) 460 m

Answer 1

In order to find the length of the boundary of the remaining park, we add two flower beds each of length 10 m and breadth 5 m, then remaining park is shown below

Now, length of the boundary of the remaining park = Perimeter of remaining park

= (90 + 5 + 10 + 95 + 90 + 5 + 10 + 95) m

= 400 m

Hence, correct option is (b)
